Description

[Detailed Description of the Invention] The present invention is an improved halogen light bulb that can be used for general lighting.More specifically, the halogen light bulb 1 is placed in the center of the concave reflector 2, and the halogen light bulb is removably attached to the socket block 4, and the concave reflector 2 is attached to the front of the socket block 4 so as to be freely engageable and detachable.A base 5 of an ordinary light bulb is attached to the rear end of the socket block 4, and the lamp is inserted into the exterior housing 6. Store socket block 4,
This relates to a halogen light bulb unit for general lighting, which is characterized by being formed by fixing a socket block 4 and an exterior housing 6.

Halogen light bulbs have much higher brightness compared to 100V, 100W normal incandescent light bulbs used in homes for the same rating, although they are smaller, so they consume significantly less electricity for the same brightness. However, due to the difference in shape, there is a large difference in the shape of the base, so it is mainly used for special purposes such as automobile headlights, copy machine light sources, and clean heaters for semiconductor manufacturing equipment. However, it was difficult to popularize it for general lighting.
Therefore, it has long been a great hope of the halogen light bulb industry to make the base of this halogen light bulb the same as that of a regular light bulb for general lighting, so that the excellent features of halogen light bulbs can be utilized for general lighting.

The present invention has been made in view of such conventional wishes, and its purpose is to provide a halogen light bulb unit for general lighting that has a structure that can be applied to general lighting.

The present invention will be described in detail below with reference to illustrated embodiments.
FIG. 1 is an external view of one embodiment of a completed product of a halogen light bulb unit A for general lighting according to the present invention, and FIG. 4 is a sectional view thereof. The socket block 4 is composed of a socket body 7 and a mounting bracket 8. The mounting bracket 8 is attached to the socket body 7, and an L-shaped engaging elastic tongue piece 10 extends forward from an annular portion 9 of the mounting bracket 8. A plurality of tongue pieces 11 are extended. A fixed cylinder 12 protrudes rearward from the bottom of the concave reflecting mirror 2, a mounting hole 13 is bored in the center thereof, and an L-shaped engagement groove 14 is formed in the inner peripheral surface. A selective transmission film is coated on the concave reflector 2, which reflects visible light forward to produce spot light, parallel light, or uniformly diffused light, and allows infrared rays to escape backward to prevent heating of the irradiated object. It's getting old. Further, the inner periphery of the concave reflecting mirror 2 is divided into fine mosaic shapes, each of which constitutes an independent reflecting surface, so that the light source is uniformly reflected. In the illustrated embodiment, a power supply hole 15 is formed in the socket body 7, and a plug blade 16 is built therein. (Of course, the socket is not limited to the embodiment shown in the figure, and a small socket (not shown) such as E11 may be provided.) An insulator section 17 is attached to the rear end of the socket body 7, as described below. For example, it is fixed to the exterior housing 6 by caulking. A regular base 5 of E26/27, which is the same as a regular light bulb, is attached to the rear half of the insulator part 17.
A cord 18 led out from the plug blade 16 is connected to the normal cap 5 and a terminal 19 provided at the center of the rear end of the insulator. The exterior housing 6 has a two-stage cylindrical shape, and a cutout 20 is caulked and fixed to an annular portion 9 of a mounting bracket 8. A large number of elongated holes 21 for heat radiation are bored in the side surface of the exterior housing 6.

Then, insert the halogen bulb 1 into the socket body 7 accurately, and then insert the fixed tube 1 of the concave reflector 2.
When the elastic tongue piece 10 is inserted while being pushed out on the outer periphery of 2 and rotated at the same time, the engagement L-shaped tongue piece 11 is locked in the L-shaped engagement groove 14, and this locking force and the elastic tongue piece 10
The concave reflecting mirror 2 is fixed to the mounting bracket 8 by the resilient force. The unit main body 3 with the halogen light bulb 1 mounted in this way is screwed into, for example, a ceiling socket (not shown). After that, when the lamp is turned on, the visible light from the halogen bulb 1 is emitted forward to form a uniform spot light, and the infrared rays are emitted to the ceiling through the long hole 21. When the halogen light bulb 1 burns out, the operation is reversed to that described above and the halogen light bulb 1 is replaced with a new one. That is, by pushing the concave reflector 2 a little and rotating it in the opposite direction, the engaging L-shaped tongue piece 1
1 from the L-shaped engagement groove 14. Pull out the concave reflector 2 at the place where it comes off, and remove the concave reflector 2 from the socket body 7. Then, the halogen bulb 1 will be completely exposed, so pull it out and replace it with a new halogen bulb 1. When the replacement is completed, the concave reflector 2 is attached again and the light is turned on. Although not shown, if a low-voltage halogen bulb 1 is used, an electronic transformer may be installed to lower the commercial voltage to a voltage suitable for the halogen bulb 1.

As described above, the present invention is such that a halogen bulb is placed in the center of a concave reflector, the halogen bulb is detachably attached to a socket block, and a concave reflector is detachably attached to the front surface of the socket block. The base of a regular light bulb is attached to the rear end, the socket block is housed in the exterior housing, and the socket block and exterior housing are fixed, so halogen light bulbs can be used in conventional regular light bulb equipment with the same handling as regular light bulbs. It is possible to use the features of halogen light bulbs for general lighting.Furthermore, since the halogen light bulb is removably attached to the socket of the unit body, it is also possible to replace just the halogen light bulb. It is extremely simple, and it is highly expected that halogen light bulbs will become popular for general lighting.
